CARD CLOTHING Filed April 2, 1964 United States Patent O 3,325,866 CARDCLOTHING Eugene V. Caille, South Barre, Mass., assignor t AssociatedDesign & Mfg. Co., Inc., a corporation of Massachusetts Filed Apr. 2,1964, Ser. No. 356,719 7 Ciaims. (Cl. 19-114) This invention relates toa novel type of card clothing, and the principal object of the inventionresides in the provision of a heavy, preferably metallic, base wire inthe form of a channel or the like which is easily provided With a fillermember upon which are arranged spaced staples, each staple presentingtwo points.extending out of the open edge of the channel member, to formclothing some- What similar to metallic clothing but having separateinserted wire staples each With two points which are somewhat similar tothe points in the filler types of card clothing. This provides for agreatly increased point population par square inch and also providingfor a more economically manufactured card clothing which has teethproviding a certain amont of resilience and providing also for easymaintenance of the sharp points heretofore impossible with metallicwire, particularly With punched teeth. The new car-d clothing is easilycleaned and is self-stripping and does not tend to break or out thefibers.

The new wire teeth can be provided with a rake which is ordinarilydesirable and this rake can be varied to any degree desired. This isdonc merely by providing for the staples to be arranged on the filler atany angularity which is desired With respect thereto, and then thefiller and assembled teeth are inserted in the channel, and the channelis squeezed at the sides thereof to hold the staples providing a strong,sturdy and substantially solid card clothing.

Another object of the invention resides in the provision of a novel cardclothing construction as above described in which the filler can beformed with tufts so that in turn the card clothing has a desirablebrushing action as well as the carding action, and in the present casethis is done very economically. The new card clothing is perfectlycylindrical when mounted on the cards on the cylinder or roll eventhough there are dents or flat spots thereon, the base wire or channelproviding for a film support for the points. The Wire can be mounted inspiral relation around the cylinder so that the various runs contacteach other tightly and are practically self-locking being held inposition, each by the other, as will be clear to those skilled in theart.

Other objects and advantages of the invention will appear hereinafier.

Reference is to be had to the accompanying drawings, in which:

FIG. 1 is a perspective view illustrating a form of the invention;

FIG. 2 =is an exploded view illustrating how the various parts areassembled;

FIG. 3 illustrates a filler having tufts or bristles therein;

FIG. 4 is a perspective view illustrating the base channel member;

FIG. 5 illustrates the filler member With the staples attached theretoat right angles with respect to the edges thereof;

FIG. 6 illustrates the filler with the teeth set at an angle, and

FIG. 7 illustrates a rubber or plastic member having a central corewhich can be used as a filler if desired.

Referring now to FIG. 1, a form of the finished clothing is illustrated.This consists first of a base wire or ferrule member in the form of achannel, this being illustrated generally by the reference numeral 10.This channel has the side walls 12 and 14 and a bottom wall 16, sec

FIG. 4. Mounted within the channel there are a series of mutually spacedstaples. Each staple has a pair of legs 18, 18 and a member 20connecting the same and closing the U, and it will be seen that thesestaples in general are in position within the channel 10 With the ends22 of the staples extending outwardly from and forming the cardingelements or points.

The staples are held in their generally parallel mutually spacedrelationship in the channel by means of a filler member 24 and when theparts have been assembled, pressure can be applied at the exterior sidewalls 12 and 14 of the channel member to substantially permanentlyconnect the parts together as shown in FIG. 1.

It is preferred that the channel member 10 be made of some strongmaterial which can be extruded or folded in the form shown. Any othersuitable material which can be formed and which when pressure is appliedthereto will substantially permanently secure the staples to the fillermember 24 can be utilized. The staples will of course -be made of theusual Wire of which card clothing points are made and the filler member24 can be of metal, rubber, plastic, or any other suitable material. Forinstance, as shown in FIG. 7, a rubber or plastic tube 26 can beutilized and particularly if it is provided with a strong ocre 28 suchas of metal, etc., it is perfectly possible to assemble the staples Withrespect to this filler and then into the channel as before.

One convenient way of assembling the parts is to first assemble thestaples in their spaced relationship shown in FIG. 1 on the filler 24 asillustrated in FIG. 2. That is, the staples are arranged in parallelrelation in the filler With the filler between the points in the areas18 and the port-ions 20 thereof close to the bottom edge of the filleror in contact therewith. Any kind of adhesive can be used for thispurpose and as shown in FIGS. 5 and 6 the staples will be retained inthis position when being assembled within the channel 10. Once theassembly is done and pressure is applied as described, a substantiallyendless wire is provided which is strong and sturdy and substantiallypermanently connected as to the teeth. Thus the objects of the inventionhave been carried out, i.e., an extremely strong and rigid card clothingis provided in which however the teeth are inserted and can be groundand have all the advantages of wire teeth. Also the teeth can beinclined angularly with respect to the filler member as is indicated at30 in FIG. 6, the filler member here hein-g indicated by the referencenumeral 32. The showing in FIG. 5 is substantially the same as thatshown in FIGS. 1 and 2.

As shown in FIG. 3, the filler can itself be formed for instance in thenature of a channel, and in this channel there can be provided a seriesof bristles or tufts. In this case the channel is indicated at 34 andthe bristles or tufts at 36. Pressure can be applied to the sides of thechannel 24 to hold the tufts in position and then the staples can beapplied to the outside aspects of the filler member 34 just aspreviously described. In this case however the member 34 does notnecessarily have to be in the form of a channel but may be in the formof a plurality -of parallel thin plates or wires assembled together andholding the bristles or tufts therebetween. Otherwise the constructionand operation is exactly the same as before.

It will be noted that when it is desired to have angular points as inFIG. 6, it is not necessary to bend them so that there are kneesinvolved, and stronger points are provided the fulcrum of pivot thereofbeing located in the bottom of the wire at the point 38 indicated inFIG. 6 rather than intermediate the ends thereof as is the usual caseWith leather foundations.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein 3 disclosed, otherwise than asset forth in the claims, but what I daim is:

1. Card clothing comprising an elongated strip in the general form of achannel having an open side, said channel forming a base, a filterdisposed in said channel, a series of separate closely spaced wirestaple elements, each wire staple element having a closed end joining apair of spaced legs, the legs of the staple elements straddling thefiller member, the elosed end of each staple element being held betweenthe bottom of the channel and the edge of the filler that is adjacentthe bottom of the channel, the legs of the staple elements extendingoutwardly from the channel at the open side thereof.

2. The card clothing recited in claim 1 wherein the channel closelyengages and grasps the staple elements in the area. of the filler andholds the staples to the filler.

3. The card clothing recited in claim 1 Wherein the legs extendgenerally normal to the filler.

4. The card clothing reeited in claim 1 Wherein the legs extendgenerally normal to the filler and are parallel.

5. The card clothing recited in claim 1 wherein the legs extend at anincline With respect to the length of the filler in the channel.

6. The card clothing recited in claim 1 wherein the legs extend at anincline With respect to the length of the filter in the channel, saidlegs being straight and parallel.

7. Card clothing comprising an elongated strip in the shape of a channelforming a base, a filler disposed in said channel and held therein, saidfiller being closely engaged by the side portions of the channel andbeing located adjacent the bottom of the channel, a series of flexibletufted members mounted in the filler and extending outwardly from saidchannel, and a series of wire staples mounted on the filler and likewiseextending from the channel t0 a greater degree than said tufts, eachstaple including spaced legs, the tufts appearing between the legs, andeach staple having a closed portion extending generally about the fillerand being held between the filler and the bottom of the channel.
